Given numbers are 258,428,515,380,629
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 258,428,515,380,629 is 339816885180.
Find LCM of 258,428,515,380,629 with Prime Factorization
| 2 | 258, 428, 515, 380, 629 |
| 2 | 129, 214, 515, 190, 629 |
| 5 | 129, 107, 515, 95, 629 |
| 129, 107, 103, 19, 629 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 129 x 107 x 103 x 19 x 629 = 339816885180
Therefore, the lowest common multiple of 258,428,515,380,629 is 339816885180.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
258 x 428 x 515 x 380 x 629 = 13592675407200
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
258 : 1, 2, 3, 6, 43, 86, 129, 258
428 : 1, 2, 4, 107, 214, 428
515 : 1, 5, 103, 515
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
629 : 1, 17, 37, 629
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 258,428,515,380,629, is 1.
Now, the common factors can be found like this.
258:2x 3x 43
428:2x 2x 107
515:5x 103
380:2x 2x 5x 19
629:17x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 5 = 40
Therefore, the value for common factors is 40.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 13592675407200/(1x40)
LCM = 13592675407200/40
LCM = 339816885180
Thus, we can understand that the LCM of 258,428,515,380,629 is 339816885180.
